When I use optimoptions with any solver name, I get the following error message:

Error using optimoptions (line 124)
Invalid default value for property 'OptionsStore' in class 'optim.options.Fmincon':
Not enough input arguments.

Looks like it does not recognize any solver. Do you know how to fix this? Thank you!

It is possible that you need to reinstall Optimization Toolbox. Or perhaps the following less drastic alternative will suffice:

clear all
rehash toolboxcache

Dear Alan,

I've tried both and nothing changed. I will try to unistall and reinstall my Matlab package.

Thanks anyway for your help!
